BACKGROUND

1. Field of the Invention

Present embodiments generally pertain to an awning assembly with powered service for electrical accessories. More particularly, present embodiments relate to, without limitation, a rotatable awning assembly with a power track formed in the assembly for connection of various electrically powered accessories.

2. Description of the Related Art

The use of awnings on recreational vehicles and fixed structures, for example on homes, has increased in part due to a desire to increase the functionality of outdoor living spaces beneath and around these awnings. Various attempts have been made to improve functionality of outdoor living spaces created in part by outdoor awnings. In doing so, a host of problems have arisen.

For example, it would be desirable to use powered accessories in the outdoor living space. However, use of electrically powered accessories has been difficult for a multitude of reasons. One problem has been related to the use of electrical wiring or power cords for the accessories. Some prior art devices have utilized awning hems to conceal wiring from the RV to the extended end of the awning. Other prior art or solutions have utilized separate joist-like structures within the awning framework to position lights once the awning has been extended. Other solutions have involved multiple power cords running to accessories. However, it may not be desirable to run a multitude of wires which may be a tripping hazard or delay storing of the awning for example, if windy conditions or weather changes rapidly.

Additional problems have involved pathways for the wires while accommodating the extension and retraction of the awning assembly. While some attempts have been made to conceal the wire in the awning hem, the rolling of the awning and wire therein may cause undesirable thickening of the awning edges when rolled.

Accordingly, it would be desirable to overcome these and other deficiencies to provide an awning assembly which allows the use of powered accessories to increase the functionality of the outdoor living space provided in part by the awning. It would also be desirable to provide additional function under and around the shaded area of the awning.

The information included in this Background section of the specification, including any references cited herein and any description or discussion thereof, is included for technical reference purposes only and is not to be regarded subject matter by which the scope of the invention is to be bound.

Alternatively, the power track awning assembly may include an awning bar wherein an extrusion has a power groove including at least one track and conductors for electrical communication with an accessory base powering an accessory, for example for use in a cassette-type awning.

Referring now to FIG. 1, a perspective view of a recreational vehicle 10 is depicted. The exemplary RV includes a drive and a transmission, not shown, as well as at least one sidewall 12 and a roof 14. It should be understood that although an RV is referred to in the exemplary embodiments, one skilled in the art should understand that the use of the awning with a power track is not limited to these drivable vehicles. The term “RV” is also meant to include towable structures, sometimes called campers, homes and other stationary structures as well as boats or other marine applications for example which use canopy structures which may or may not be retractable, commercial vehicles, agricultural vehicles, horse trailers, and temporary structures such as those used at sports events, (tailgating), flea markets. All of these structures are considered to be usable with the power track awning assemblies of the present embodiments.

An awning assembly 20 is connected to the sidewall 12 and/or the roof 14 of the vehicle 10. In further embodiments, the awning assembly 20 may be retractable within the sidewall 12 so as to reduce the airflow interference of the assembly while the vehicle 10 is being operated.

The awning assembly 20 includes an awning or canopy 22 and hardware assembly 28 defined by at least one first arm 24 and at least one second arm 26. The awning hardware assembly 28 which is utilized according to the instant embodiment to connect the awning assembly 20 to the sidewall 12 of the vehicle 10. The hardware assembly 28 allows for support of the canopy 22 in an extended position (shown) or in a retracted position. The hardware assembly 28 also provides a pathway for wiring from a power source to the awning roller tube to power an accessory or power the awning motor. The awning assembly 20 is exemplary and other variations may be utilized. Also, the roller tube assembly may be movable as shown, or may be fixed to the sidewall 12. Further, for example, according to some embodiments, a cassette style awning may be utilized.

The depicted awning assembly 20 further includes a roller tube assembly 30 which moves inwardly and outwardly with corresponding retraction or extension of the canopy 22 to provide the sheltered or shaded area beneath the awning assembly 20. The awning assembly 20 may be a manually operated assembly requiring manual rotation to extend or retract the canopy 22. Alternatively, the awning assembly 20 may be an automated system such as by electrical, air, hydraulic or other fluid power systems to cause extension or retraction of the canopy 22.

The power track awning assembly 30 is shown in extended position with various accessories 32 located therein. For example, the assembly 30 depicts a pair of pendant track lights 32 depending from the awning roller tube which provide illumination for the area beneath the awning assembly 20. While pendants are shown, other types of lights may be utilized and this description should not be considered limiting. Additionally, a fan accessory 34 is shown spaced from the pendant lights 32. The fan accessory 34 creates an air flow beneath the awning assembly 20 which aids to provide a cool feeling in the area and move air so as to reduce the amount of insects in the area beneath the awning. These accessories 32, 34 are merely examples and not limiting as various other accessories may be utilized such as audio-video equipment for example, wireless speakers, television 36, or the like, all of which may be powered by the power track awning assembly 30 and all of which are collectively referred to as accessories.

Referring now to FIG. 2, the power track awning assembly 30 is shown in isometric view removed from the awning 22 (FIG. 1) and hardware assembly 28. Assembly 30 includes an awning roller tube 50 having a first end 40 and a second end 42. Rotation of the roller tube 50 is provided between fixed top castings 44, 46 and bushing structures which allow for rotation of end caps 48, 49 and the roller tube 50. A rotatable conductor 60 (FIG. 3) is provided at one of the first and second ends of the assembly 30 to provide electrical power for a power groove 52. The power groove 52 extends between the first end 40 and the second end 42 of the assembly 30 and may extend continuously through the entire roller tube 50 or may extend partially between the first end and the second end. Additionally, a single power groove 52 is depicted however, multiple grooves may be utilized in alternate embodiments. For example, multiple grooves may be used which are axially aligned. Also, multiple grooves may be used which are spaced apart circumferentially about the awning roller tube.

An accessory base 54 is depicted in the groove 52 and makes powered connection for various accessories. The accessories may be connected to the base 54, to provide power from the groove 52 to any of the accessories for example, 32, 34, 36.

At the first end of the power track roller tube assembly 30 is a power wire 41 with a connector. The wire 41 in the exemplary embodiment provides power to a motor which causes rotation of the roller tube 50 and end caps 48, 49. At the opposite end, a second wire 43 is depicted extending from the second top casting 46 and provides power for the power groove 52 and accessories connected to the accessory base 54. The wires 41, 43 are connected to additional wiring which runs through the hardware 28 and therefore, remains substantially hidden from view and from possibility of entangling with other structure or during the use of the awning assembly 20 (FIG. 1). For example, with brief reference to FIG. 10, an exemplary routing is shown wherein the wiring is shown passing through the hardware assembly. The wiring is depicted as a broken line and raised from the hardware assembly 28, but in actual use is positioned within the hardware assembly 28. Specifically, in the depicted arrangement, the hardware 28 includes a first arm 24 mounts to a sidewall of an RV or fixed structure. A second arm 26 is pivotally connected to the first arm 24 and a third arm 27 is pivotally connected to the second arm 26. The wiring extends through the third arm, through the second arm 26 and to the first arm where it may extend upwardly or downwardly. The arms 24, 26 of the hardware assembly 28 may be closed cross-section structures or may be open or a combination thereof.

Referring now to FIG. 3, an exploded isometric view of the power track awning assembly 30 is depicted. The awning tube 50 has a rod 51 with a torsion spring 53 wrapped thereabout which extends coaxially through the tube 50. This torsion spring 53 serves to assist the motor in closing the canopy 22, and helps to control awning extension. The rod 51 is connected to a rotating conductor 60 which extends through the end cap 49. The rotating conductor 60 allows for transmission of electrical voltage and current from the fixed part of the assembly, which is the top casting 46, into the rotating portion of the assembly, including the roller tube and to the tracks 70, 72. This precludes wrapping or binding of electrical wires. The end cap 49 is connected at a second end 42 of the assembly 30. The first end 40 of the assembly includes the end cap 48 and top casting 44 which are connected to a motor assembly that extends into the tube 50.

In this view, the tube 50 is shown with the power groove 52 extending axially through the tube 50 from the first end 40 toward the second end 42. As previously described, the groove 52 may extend completely through the groove 52 in the axial direction or may extend partially. Further, while one groove 52 is shown, multiple grooves 52 may be utilized in extending from a first end piece toward a second end. Additionally or alternatively, multiple grooves 52 may be spaced circumferentially about the tube 50.

Exploded from the power groove 52 are first and second tracks 70, 72. The tracks provide conductors 84, 85 (FIG. 5A) which are engaged by the accessory base 54 to provide power to an accessory attached to the roller tube 50. Two tracks are shown but the tracks may be formed as a single structure and located within groove 52.

According to the instant embodiment, the power groove 52 extends completely through the roller tube 50. The groove 52 is covered at ends by the covers 61, 63. One of covers 61, 63 may be cosmetic in function serving to create a symmetrical appearance with the opposite cover 61, 63. The other of covers 61, 63 may be a power-in feed cover which transfers power from the rotating conductor 60, and functions as a plug to power the track conductors 84, 85 within the tracks 70, 72. Additionally, the exemplary rotating conductor 60 is further shown and described in co-pending U.S. non-provisional patent application Ser. No. 14/278,036, titled, “Rotatable Awning with Illumination” filed May 15, 2014 by Taylor, all of which is incorporated herewith.

With reference now to FIG. 4, an isometric view of a power-in feed cover 63 is shown. For purpose of orientation, the depicted side of the cover 63 faces the interior of the roller tube 50 and groove 52 and is positioned within the groove 52 of the awning roller tube 50. The cover 63 is positioned at an end of the groove adjacent to roller cap 49, for example, on one side and the tracks 70, 72 on the other side, in an axial direction. The cover 63 includes a housing 64 which may be formed of various materials which are molded, cast or otherwise formed of non-conductive materials. Extending from the cover 64 are first and second cover conductors 65, 66. The conductors 65, 66 define portions of a circuit which provides electrical communication between the rotating conductor 60 and the tracks 70, 72 having conductors 84, 85 therein. Thus the cover 63 functions to provide a power-in feed to the tracks 70, 72. Also, located on the housing 64 is a third cover conductor 67 (see also FIG. 5A) which provides a sensor for detecting the presence of accessories. The conductor 67 comes in contact with third conductor strip 89 (FIG. 5A). When conductor 67 comes in contact with strip 89 it completes a circuit to ground. This grounding action communicates to an awning controller or other circuit for purpose of decision making chart 200 that an accessory 32 is installed in the power groove 52. If an accessory in not present, then the ground circuit is open and the awning is allowed to roll up. If the ground circuit is closed, the awning is not allowed to roll up. Thus the system functions as a safety device. The conductor 65, 66, 67 may be formed of various materials including, but not limited to, copper, brass of other electrically conductive material types.

Referring now to FIG. 5, a section view of the power track awning assembly 30 is depicted. In this view, the roller tube 50 is shown. Additionally, a plurality of axial grooves 55 are shown in the tube 50 for connection of the canopy 22 to the roller tube 50. The tube 50 includes the power groove 52 formed integrally with the tube 50. The tube 50 may be extruded of various materials including, but not limited to, aluminum which has light weight but high strength characteristics.

With additional reference to FIG. 5A, within the power groove 52 are the first and second tracks 70, 72. The tracks 70, 72 are retained in position by a plurality of locating ribs 74, 76. The ribs 74, 76 locate the tracks in desired positions within the groove 52 and inhibit undesirable movement. Specifically, the first track 70 is retained by at least one first locating rib 74. In the exemplary embodiment, there are two ribs 74, 75 which locate the first track 70 in a desired position within the groove 52. Similarly, with regard to the second track 72, at least one retaining rib 76 is utilized to locate the track 72. In the exemplary embodiment, the track 72 is positioned with two retaining ribs 76, 77.

With references still to the detailed section view of FIG. 5A, of the roller tube assembly, accessory base 54 is disposed within the groove 52. The accessory base 54 includes a power head 95 which extends into the groove 52. The power head 95 includes a pair of conductors 93, 94 which also engage conductors 84, 85 in the tracks 70, 72 to complete a circuit and any of the exemplary power accessories 32, 34, 36 which are mounted to the accessory base 54.

Also shown in this view is an electrical strip 89. As with the tracks, 70, 72, the electrical strip 89 is located with a rib 75 a, adjacent to rib 75. The electrical strip 89 is engaged by a third contact 96 extending from power head 95, as well as third cover conductor 67 and provides a safety feature. According to some embodiments, the third contact 96 may be a spring contact while according to other embodiments, the contact 96 may be a solid contact. Since the canopy 22 (FIG. 1) wraps about the roller tube 50 when the assembly 20 is stowed, the accessory base 54, including any accessory, should be removed from the power groove 52 before the canopy 22 is wrapped. The electrical strip 89 and third contact 96 inhibit operation of the awning motor when the accessory base 54 is disposed in the groove 52. As a result, the awning assembly 20 cannot be stowed when an accessory is located in the power groove 52, inhibiting damage to the awning assembly 20 or the accessory.

Referring now to FIG. 6, the first and second tracks 70, 72 are depicted removed from the power groove 52. Each track has an extrusion body 71, 73 which is generally U-shaped. Extending from near one end of the U-shaped extrusion bodies 71, 73 are ribs 78, 79 and 81, 82. The extrusion bodies 71, 73 further comprise arms 80 which, when viewed in FIG. 4, limit vertical movement by engaging the ribs 74, 76. Each of the extrusion bodies 71, 73 further defines a cavity 83 wherein conductors 84, 85 are located. The conductors 84, 85 provide power to the accessory base 54 when the base moved to a preselected position. The extrusion bodies 71, 73 further comprise a plurality of laterally extending ribs 86, 87 which space the tracks 70, 72 from the walls of the power groove 52.

One skilled in the art should be aware that while two tracks 70, 72 are shown, the instant embodiment should not be limited. For example, a single track structure maybe formed which houses and separates both conductors 84, 85 and therefore such embodiment is also considered within the scope of the instant disclosure. Further the at least one track, or two track 70, 72, may be formed in a plurality of manners. In one embodiment, the bodies 71, 73 may be coextruded with a metal defining the conductors 84, 85. The conductors 84, 85 may be formed of copper, brass or other conductors according to the non-limiting description. The extrusion bodies 71, 73 are generally non-conductive so as to insulate the conductors 84, 85 from touching other components of the groove 52 or any part of the roller tube 50. For example, the bodies 71, 73 may be formed of polymerics or plastimerics including but not limited to vinyl, polyethylene, HDPE, LDPE and like materials. It is desirable that these materials be non-conductive. According to a second embodiment, the conductors 84, 85 may be pre-formed and added to the bodies 71, 73 when the bodies are formed, such as by extrusion, molding, casting or other forming process. According to a third embodiment, the conductors 84, 85 may be joined in manual or automated fashion after the bodies 71, 73 are formed independently.

As with the description of the power groove 52, the tracks 70, 72 may be formed of various lengths. The length may depend upon the length of the groove 52 and may extend for the entire length of the roller tube 50 or may extend some length less than the length of the roller tube 50. Additionally, more than one groove 52 may be formed in the tube 50 and therefore, more than one pair of tracks 70, 72 may be formed to be positioned in the tube 50.

Referring now to FIG. 7 an isometric view of an accessory base 54 is depicted. The base 54 comprises a flange 90 including at least one aperture 92 for connection of the accessory base 54 to an accessory, such as the accessories 32, 34, 36 previously depicted in FIG. 1. The base 54 may be formed to be interchangeable with various accessories. The flange 90 is shown as a square shape with two apertures 92. However, the flange 90 may be formed of various shapes corresponding to the shapes utilized for the corresponding shapes of the accessories and therefore, this depicted embodiment is not limiting. Extending through a lower surface of the flange 90 are first and second contacts 93, 94 which extend into a power head 95 and turn so as to extend outwardly from the power head 95. The power head 95 has a first dimension d₁ and a second dimension d₂. The first dimension d₁ is less than an opening dimension in the power groove 52 so that the head may be inserted into the groove 52. The second dimension d₂ extends between the first and second contacts 93, 94 and is greater than d₁. The second dimension d₂ is greater than the opening dimension of the power groove 52 so that when rotated, the power head 95 and accessory base 54 are locked into position within the power groove 52. Further, when the rotation of the power head 95 and accessory base 54 occurs, the first and second contacts 93, 94 engage the conductors 84, 85 of the tracks 70, 72. Thus, with reference again to FIGS. 5-7, one skilled in the art will understand that the various ribs of the power groove 52 and the extrusions 71, 73 provide a locating functionality for the tracks 70, 72 and more importantly, the conductors 84, 85 so that the contacts 93, 94 may be reliably installed into the power grooves 52 and engage the conductors 84, 85. Extending from the power head 95 is a third contact 96. The third contact 96 engages an electrical strip 89 (FIG. 5A) extending through the power groove 52. When the contact 96 engages the strip, a circuit is defined such that the motor of the awning assembly 20 cannot rotate the awning roller tube 50. Thus, any accessory that is installed, for example accessory 32, should not be damaged due to inadvertent starting of the awning roller. However, when the accessory base 54, and necessarily accessory connected to the base 54, is removed and the third contact 96 disengages the electrical strip 89 (FIG. 5A), the awning assembly 20 may be rotated from the extended position shown in FIG. 1 to a closed a stowed position without risk of damaging any accessories.

Referring now to FIG. 8, an exploded isometric view of the accessory base 54 is depicted. The flange 90 is exploded from the first and second contacts 93, 94. It should be clear to one skilled in the art that the contacts 93, 94 extend through the flange structure 90 and depend outwardly so as to pass from the flange 90 and out from the power head 95. The power head 95 is also shown to be formed of two pieces 95 a, 95 b which are fastened together and allow for ease of assembly of the right angle contacts 93, 94. Additionally, the third contact 96 is shown which extends from a hole in the power head cover 95 b so that the spring contact 96 may engage the electrical strip 89 within the power groove 52 and complete the safety portion of the circuit previously described.

Referring now to FIG. 9, a side isometric view of an alternate cassette awning assembly 120 is depicted. One skilled in the art will understand that cassette awnings differ from that of the previous embodiments wherein the roller about which a canopy 122 wraps is located at a fixed end of the assembly 130, for example against a wall of a stationary structure such as a house or commercial building or alternatively, a side wall of the RV 10 (FIG. 1). The tube assembly 130 is generally fixed in the instant embodiment and at an opposite end is defined by an extending bar 131 which moves toward or away from the fixed rotating awning assembly 130. Between the bar 131 and the roller assembly 130, is a hardware assembly 128 which comprises pairs of first and second foldable arms 124, 126. These arms 124, 126 defining the hardware assembly 128 provide support for the awning or canopy 122 extending from the roller assembly 130 to the bar 131. This is a general description of a cassette awning and other constructions may differ, and therefore this should be considered a non-limiting description of merely one embodiment which may be utilized in combination with an extrusion 151.

With further reference now to the detail view of FIG. 9A, the extrusion body 151 is formed of an arm which may be tapered or angled relative to the bar 131 or may depend vertically, downwardly from the bar 131. According to other embodiments, the extrusion 151 may be formed to extend outwardly and generally parallel or at a slight descending angle relative to the ground. The extrusion 151 may have a plurality of retaining channels 157 for either retaining portions of the awning 122 or other accessory products which may be desirably used with the cassette awning 120. Toward a lower end of the extrusion 151 is a power groove 152 which comprises an opening as in the previous embodiment for retaining at least one track having at least first and second conductors 184, 185. According to instant embodiments, two tracks 170, 172 are shown wherein the power groove 152 further comprises ribs 174, 175 and 176, 177 to retain the tracks 170, 172 in position and properly locate the tracks 170, 172 therein.

The tracks 170, 172 comprise bodies as previously described with ribs which also aid to locate the tracks 170, 172 within the power groove 152. The tracks 170, 172 further comprise conductors 184, 185 which are engaged by an accessory base as with the previous embodiment. Thus, the extrusion 151 provides a system for providing power through the awning assembly 120 and to the power groove 152 such that powered accessories may be utilized when the awning 120 is in an extended position.

As with the previous embodiment, it would be desirable to route wiring which extends between the extrusion 151 and the RV 12 (FIG. 1) or fixed structure through the hardware assembly 128. Accordingly, wiring may run through the arms 124, 126 to the bar 131 wherein the wiring may be routed from the bar 131 to the power groove 152 and through a power head (not shown) to an accessory.

Referring now to FIG. 11, a control logic flow chart 200 for use of the power track awning is depicted. The use of the awning by itself is controlled in part by an awning switch 210 which is in electrical communication with a controller, circuit or other arrangement which allows for input and output based on preselected criteria to determine whether or not to supply power to the power track for powering an accessory 32. The awning switch 210 according to one embodiment may be a three position switch, for example with a neutral center position and first and second temporary positions meaning the switch must be held to either extend or retract the awning. The awning may also be retracted with the switch 210. When the switch 210 is disposed in a manner to retract 212 the awning, the awning motor 214 is powered to retract the awning at 215. When the awning is retracted, the power groove 52 is disabled. That is, the tracks 70, 72 are not powered.

Alternatively, if the awning switch 210 is moved to a position so as to extend the awning, the awning motor 214 rotates and causes the awning to extend 216. As the awning extends, the system 200 is continually determining whether the awning is fully retracted. A determination is made as to whether the motor amperage exceeds a preselected level. When the amperage exceeds the preselected amount, this represents a condition wherein the awning is fully extended causing the motor 214 amperage to rise above a desirable range. If the answer is no, the motor 214 continues to extend the awning. If the amperage exceeds the preselected amount 218, the motor 214 backs the roller up some amount or reverses from some preselected time period at 220. At this time, power is supplied to the track of the groove 52 at 226.

Once the awning is extended, the power track is enabled for operation. This means that power is provided to the power groove 52 and may be controlled by a second switch 230. The second switch 230 controls power to the accessory 32. In one position, the power switch 220 may provide power to the accessory at 232. In a second position, power is not provided to the accessory at 234 but instead is available once the power switch 220 is actuated.

While several inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the invent of embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teaching(s) is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.

All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms. The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases.

Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.

As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited.

In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.
